Your media player is equipped with a variety of features. To help you maximize your
listening pleasure, SanDisk would like to advise you that it is important to use your
headphones with your media player at a safe hearing level.
• Exposure or repeated exposure for an extended period of time to music and
other sounds that are too loud can cause damage to your hearing resulting in
temporary or even permanent “noise induced hearing loss”.
• Symptoms of hearing loss increase gradually with prolonged exposure at high
levels of loudness.
• Initially, you may not even be aware of the loss unless detected with a hearing
test.
HEARING LEVELS
To help you understand what may be considered a safe hearing level, the following
examples are included for your reference.
Examples of Typical Approximate Sound level:
- Sound Levels in Decibels (dB)*
- Refrigerator humming 40
- Normal conversation 60
- City traffic 80
- Motorcycles and lawnmowers 90#
- Rock concerts 110-120#
- Firearms 120-140#
* A decibel (dB) is a unit of relative measurement of the strength of sound wave.
In decibels (dB), a measured signal level doubles with every additional 3 dB.
# These sound levels are considered harmful under extended exposure.

FOR YOUR SAFETY!
• Your hearing may adapt to higher volumes of sound. In order to prevent any
harmful impact to your hearing, you must control the sound emanating from
your headphones and set the media player volume to a low setting where you
can hear it clearly and comfortably.
• Studies, including one from NIDCD indicate that sounds of less than 80 decibels,
even after long exposure, are unlikely to cause a hearing loss.
• Listen to your media player at such a level that you can still hear conversation
and other people in your environment without shouting when you attempt to
converse.
• It can also be dangerous to play your music with headphones/earphones at high
volume while walking, or engaged in other activities. You should exercise
extreme caution and discontinue use in potentially hazardous situations.
Do not use headphones/earphones while driving, cycling, or operating any
motorized vehicle. This may create a traffic hazard and may be illegal in some
areas.
